It was built as an ironmaster's house and later enlarged by Franklin Swayne.","why_significant":"The nomination argues the building is significant for its distinct and unusual architectural character, which combines designs from the 18th, 19th and 20th centuries into a balanced, continuous structure. Its central main section has a floor plan with a longitudinal front hall and central chimney that the nomination says is not typical of the area. The Swayne alterations are described as imitating early English design, and the front facade is described as a combination of Palladian and neo-Greek features.","narrative":"Stone construction began in the late 18th century on this site in Wagontown, Chester County, when an ironmaster's house was completed in 1798 with a stone kitchen addition and a large fireplace. A central mansion section was built around 1821 after Charles Brooke purchased the property, featuring a longitudinal front hall and a central chimney with two fireplaces on each floor. Between 1895 and 1910, Franklin Swayne added a heavily pedimented pavilion, a stone ballroom wing, quarter-round connecting additions, and a double-gabled service ell. The nomination regards the main section's floor plan, high ceilings and spacious rooms as unusual for the area. Swayne's additions are described as imitating early English design, and the front facade blends Palladian and neo-Greek features, giving the house its distinctive character.","period_of_significance":null,"architect_builder":null,"architectural_style":"Georgian-Federal interior woodwork; Palladian and neo-Greek front facade features; alterations imitative of early English design","criteria":[],"status_note":"The building is shown with a stuccoed exterior and metal roof over most sections; the west ell is used as the residence of the Park superintendent.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:30.84678-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/75001632.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/75001632/ee9256e6ec-800.webp","url_1600":"https://nationalhistoricalregister.com/media/75001632/ee9256e6ec-1600.webp","licence":"CC BY-SA 3.0","author":"Choess","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Back_of_Hibernia_Mansion.jpg\" rel=\"noopener\">Choess</a>, <a href=\"https://creativecommons.org/licenses/by-sa/3.0\" rel=\"license noopener\">CC BY-SA 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Back_of_Hibernia_Mansion.jpg"},"district":{"nrhp_refnum":"84003205","name":"Hatfield-Hibernia Historic District","url":"https://nationalhistoricalregister.com/districts/pennsylvania/hatfield-hibernia-historic-district-84003205/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71998491","wikipedia":"https://en.wikipedia.org/wiki/Hibernia_House","wikidata":"https://www.wikidata.org/wiki/Q5750717"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/chester-county/hibernia-house-75001632/"}
